Application filed January 26, 1922. Serial No. 532,907.

To all who 2a it mag concern:

Be it known that I, Ann/inner E. GoonwiN, a citizen of the United States of Amen ica and a resident of Newburyport, in the county of Essex and State of hlassachusetts, have invented certain new and useful I1nprovements in Hinged Lasts, of which the following is a specification.

This invention relates to hinged lasts and has for its object the production of a device of this character which will be simple in construction, durable in use, and easy to assemble.

The invention consists of a two-part last, the heel part of which has anchored therein a pin socket provided with a flat sided extension projecting intoa vertical slot in the fore part and secured to said fore part by means of a hinge pin.

The invention further consists of certain novel features of construction and arrange ment of parts which will he understood readily by reference to the description of the drawings, and to the claims to be here inafter given.

For the purpose of illustrating the invention, one preferred form thereof is shown in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangement and organization. of the instrumentalities herein shown and described, except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents an elevation of a hinged last embodying the principles of the present invention.

Figure 2 represents a longitudinal section of the same with a portion of the fore part in elevation.

Figure 3 represents a plan of the hinge member.

Figure 4 represents a side elevation of the same, and

Figure 5 represents an end elevation of the same.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings 10 is the heel part of a by means of the last and 11 the fore part thereof. In the heel part 10 are disposed two abutting plates 12 havin concavities 13 formed therein to form a pin socket i i. The upper ends of the plates 12 areprovided with outwardly extending flanges 15 superimposed upon the upper face of the heel part 10, these flanges 15 having an outline conforming to that of the upper end of said heel part 10.

The plates 12 are secured to the heel part 10 by means of the pins 16 and ii. The front ends of the plates 12 have forwardly projecting extensions 18 which are disposed within a vertical groove 19 in the rear end of the fore part 11.

The side walls of the plate 12 abut against the side walls of the vertical slot 19. A hinge pin 20 positioned in the fore part 11 passes through the extensions 18 and forms a hinge connection between the heel part 10 and the fore part 11, and about the axis of which said parts are moved rela- .tively to each other when it is desired to shorten the last.

In the rear end of the fore part 11 is a socket 21 in which is disposed one end of a spring 22. the opposite end of which is disposed in a depression in the front face of the heel part 10. The end of the spring 22 positioned in the depression 23 is prevented from being accidentally displaced therefrom projection 24 formed upon the front edge of the plates 12. The upper end of the socket 21 is elongated in order to accommodate the change in position of the spring 22 when the heel part 10 and fore part 11. are moved relatively to each other about the axis of the pin 20.

The heel part 10 is provided with a transverse shoulder 25 which is adapted to coact with the transverse shoulder 26 on the rear face of the fore part 11. These shoulders 25 ane 26 are adapted to contact when the last is straightened and to move from each other when the last is shortened.

It wil be noted that in the construction herein shown and described, the pin socket 14 and the hinge member 18 are formed integral and when positioned in the heel part 10. said hinge member is securely anchored thereto.

By forming this hinge member of two plates abutting each other. it is possible to form thereon the flanges 15 which will thoroughly protect and strengthen the heel part of the last during the lasting operation.

This makes a very strong last, the parts of which are reduced to a minimum. various parts may be easily and quickly assembled.

It is believed that the operation and many advantages of the invention will be readily understood without further description;

Having thus described my invention, claim:

1. A two part last having two plates positioned in the heel part, face to face, and pro vided with concaved portions forming a pin-receiving socket and having a forward extension positioned in a vertical slot in the fore part; a hinge pin in said fore part passing through said extension; and a spring between said parts.

2. A two part last having two plates positioned in the heel part face to face, and provided with concaved portions forming a pin-receiving socket and having a forward extension positioned in a vertical slot in the The fore part; a hinge pin in said fore part pass- I in the fore part; a hinge pinin the fore part in front of its rear face and extending through said extension; and a spring between said parts, one end of whlch is positioned in said recess and the other end of ABRAHAM E. eoonwm- \Vitnesses i l/VALTER E.
